Beast release jutsu's:

Chakra claws: in human form a waldes member can force chakra out of the tips of their fingers into the shape of claws

Thunder clap: the waldes force chakra into their hands and clap them together sending the wave of chakra forward about 10m or 32 feet, the wave doesn't look the same for all members, others have thinner ones that are more powerful and concentrated, other are very widespread and mostly are to knock back or disrupt an opponents attack

Death Roar: the Waldes death roar is their pride and glory, they force chakra into their mouth then release it into a thunderous roar that sends out a cone of highly concentrated chakra

Beast Release Stages:

Stage 1: the waldes member can turn to their spirit animal increasing their chakra and changing their jutsu style based on their spirit animals chakra type

Stage 2: the waldes beast form now has the ability to absorb chakra from incoming justu's, but not the person personal chakra. in human form the noticing change is their hair has some white strands

Stage 3:the waldes beast form is now able to devour the chakra of summoned being, but the increased chakra pool in the person body cause them to become slightly unstable sometime making them do things they wouldn't usually do. in human form their hair becoms completely white

Stage 4: the waldes beast form now has spines on their arms and back thus allowing for a more lethal being, the person becomes even more unstable and will sometimes turn on their own if they lose their train of thought

stage 5: the waldes final form allows their beast form to fully integrate with them, they lose almost all sense of being human and become more animal like, and can easily be thrown into a frenzy, the power it gives them is the use of the swift release
